SASH-FASTEN ER.

SPECIFICATIONforming part of Letters Patent No. 574,727, dated January 5, 1897.

Application filed April 1, 1896. Eierial No. 585,685. (No model.)

To ztJZ whom it may concern.-

Be it known that I, ALBERT M. FRASIER, a citizen of the United States of America, residing at Penn Station, in the county of \Vestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Sash Holders and Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in sash holders and locks, and has for its object to construct a holder that will securely retain the sash at any desired point, and when the window is lowered to its normal position will securely lock the same and prevent it from being raised from the outside.

A further object of the invention is to construct a sash holder and lock of the abovedescribed class that will be extremely simple in its construction, strong, durable, effectual in its operation, and comparatively inexpensive to manufacture; furthermore, that will not deface the window-frame by reason of the holder being in engagement therewith.

With the above and other objects in view the invention finally consists in the novel construction, combination, and arrangements of parts to be hereinafter more specifically described, and particularly pointed out in the claim.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like letters of reference indicate similar parts throughout the several View in which- Figure 1 is a front view of a portion of the window and frame, showing my improved sash-holder block in position. Fig. 2 is a vertical sectional view of the casing, showing the perspective parts in position. Fig. 3 is a side view of the sash-holder. Fig. 4 is a similar view of the locking device. Fig. 5 is a view of a portion of the frame, showing the lockingplate in position.

In the drawings, a represents the casing, which is formed in two sections, preferably secured together by clamping the end of one section over that of the other. Apertures b b are through the sections of the casing, near each end, which are adapted to receive screws 0 c, which are of sufficient length to extend into the sash d and fasten the casin g thereto.

' W'ithin the two sections is pivotally secured a plate 6, which is tapered and provided with a catch f on the small end. This plate e is pivoted to the casing at a point above the middle of the plate, thus causing the same to hang in an inclined positionwith the smaller end upward and extending outward between the two sides of the casing. This larger end is formed with teeth g g, and a rubber strip h or other pliable material is secured to this end of the plate and is formed with a corrugated face i, which engages the window-frame j. The underneath casing ct is provided with a flange it, which is curved at both ends, forming clamps for the triangular-shaped spring Z, which supports the platec and prevents the same from hanging in a perpendicular position. The other arm of this triangular-shaped spring rests on the flange m, provided on the upper edge of the locking-plate n, which is pivotally secured in the casing near the lower end of same. This looking-plate is held in an upwardly-inclined position by a projection or lug 0, formed on the underneath plate of the casing, and is provided witha V-shaped groove 19 in the upper end, forming a projection g, which engages in the slot 7' of the plate s, secured to the window-frame. A catch or lever tis secured to the plate n and operates, through a slot to in the casing Cb, for withdrawing the catch (1 from engagement with the plate .9 when it is desired to raise the window.

The operation of my improved sash holder and lock will be readily apparent from the views of the same which I have shown in the drawings.

When the parts have been secured in their respective positions, the holder is fastened to the sash near the base of same, and when the sash is lowered to the window-sill the projections q of the locking-plate will be forced into the slot in the plate 8 by reason of the pressure of the spring on the top of the plate, securelylocking the window in its normal position and preventing the raising of the same from the outside.

\Vhen it is desired to raise the sash and suspend the same at any desired height, the locking-plate is released by a pull on the lever z, and the window can then be raised to the desired height, and the corrugated rubber surface engages the sash and retains the window securely in position. When it is desired to lower the window again, pressure is brought to bear on the catch or button f, which will release the corrugated rubber from the frame and allow the window to descend, and when it reaches the sill the lock will again engage in the plate a and the window is securely locked.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I11 testimony whereof I affix my signature 0 in presence of two witnesses.

ALBERT M. FRASIER.
